The fire began about 6:35 a.m. Thursday at a vacant home in the 3200 block of Hickory Stick Road near 122nd Street and May Avenue. Two workers were entering the home to inspect it when the blaze began near the heater.

Fire officials said the inspectors then climbed onto the roof of the home and tried to douse the fire with a garden hose. Firefighters arrived minutes later and said they quickly put out the fire.

"They did the right thing to call us first, but their efforts also helped us a little bit," said Chief Steve Lumry with the Oklahoma City Fire Department.

No one else was inside the home. The home is valued at $300,000 and the damage was only about $2,000.

The cause of the blaze is under investigation.
